Has anyone else had this problem. I always have trouble cuming when fuckin my Gf i always get close but nothing i always have to jerk my cock and then slide it in her pussy or mouth to cum. Any advice or help
Definitely can't help you with that from a fully balanced performance standpoint as I have the opposite problem. Although I have great staying power when it comes to other sexual activity when actually engaged in intercourse I cum within less than a minute most times and actually far too often within a few strokes.
My suggestion is to mentally work yourself up into a highly charged sexual state employing any real or imagined and fantasized scenarios. Only you know what can act as a mental stimulus.
For my problem I actually have tried to imagine everything I can to destimulate but getting the balance right is very difficult as too much of a turn off can obviously kill desire completely and that of course can be misinterpreted by your partner as a lack of desire for them.
I am sure that could be a problem in your case especially if it is a new relationship or ships passing in the night thing. That potentially is as bad as my problem of disappointing with my tiny penis and no stamina. Although it is clear that I am def turned on it is generally a cause for them to be turned off and left wanting.
Perhaps you need to explore more ways to expand and enlongate foreplay to raise your stimulation levels. I spend a lot more time on it in the hopes of raising the other persons levels and increase the chances of giving them more pleasure in other ways even if my penis doesn't.
Having said all that I have occasionally had difficulty maintaining a full erection when the woman I am with has a far too loose pussy Either by just naturally being way too big for my skinny cock or when I have attempted sloppy seconds after a much better endowed guy has fucked her and she is stretched and extra full of juices ( hers and his if he hasn't used a condom)
Our problem is similar as we both for different reasons can struggle to satisfy but at least I always can cum without any digital stimulus. ( I do feel a bit selfish and disappointed afterwards though if I know my partner has been left unsatisfied)
Anyway my advice is to work on mental stimulation. Couples in long term relationships can suffer from staleness and a certain level of ambivalence if things become too routine no matter how physically proficient he is as a cocksman or either or in their general sex play.
It doesn't always require some change to the physical side of it but mental foreplay with each other can reap benefits. For example bringing a third party ( or more ) to spice things up isn't for everyone but expressing the fantasy of it may be a kick in itself. In general just fantasizing for yourself or sharing fantasies with your partner can in my experience be hugely arousing even if their is no intent to act on them.
There was a time I thought I was in a cul de sac or dead end in regards to my tiny cock/ no stamina situation but I have long been past that thanks to my own SPH fuelled fantasies (as well as a host of other variants) and the great fortune of crossing paths with women who aided and abetted sexual experiences by indulging them physically in some cases but also by simply sharing our fantasies verbally or watching porn in some cases.
Unless there is some actual physical reason for your "dis function" then I believe it is a mental stimulus problem. The fact that you have no trouble cumming otherwise suggests it is a the latter. If this is indeed the case then I think you can definitely overcome it. I have had a lot of enjoyment tackling my issue with various partners but outside of that I have discovered a still expanding train of thoughts and fantasies that greatly enhance my alone with just my hand sessions (unfortunately that is more often than not due to the pandemic restrictive inconveniences even if my gf and I share a "bubble" in theory in reality we are rarely in the same place indoors and even then we are careful about physical contact as we live separately and due to our work situations cross paths with too many others and are acting cautiously.
The truth is we are relegated to a lot of masturbation either alone, phone sex and a few times watching each other as we watch porn and or enjoy sex banter ( a lot of that is imagining what we could do when this corona thing is history)
In other words mental stimulation is absolutely key. You can potentially "talk your cock " into responding.
